Sendra
Post-ban receivers have a circle milled into the side of the magwell. They were originally bead-blasted to a non-glare finish. All others are pre-ban. (This is unverified info…) Also, they used to be NESARD. Rumored to have been owned by Dick Drasen (currently M&A Parts) and produced lowers only out of Barrington, Illinois. No complete guns were sold (again, unverified info).

Sendra is also one of those mentioned by ATF in their book as being assembled with certain M16 parts, which is now a big no-no to them.

As for value, I couldn't say. I would imagine it would be up there with other pre-bans...
